MECHANICAL TQYQ To all whom it may concern:

Be it known that I, JOHNHMORAN MUR- my, a subjectiof the King of Great Britany required length,

ain, residing in Kingstown, Ireland, have invented a certain new and useful Improved Mechanical Toy, of which the following is a specification. i

' The inventionconsists in a mounting for model ships, tanks or the like by which they may be manipulated so as to travel over a suitable surface at varying speeds and in any required direction.

The models mounted in this manner lend themselves to a naval game in-which con voys may be attacked, battle ships may endeavor to elude submarines, or two vessels may race to a given point.

The models are supported by a pair of wheels, running freely on axles at the same transverse section, and by a member provided with two claws placed in the fore and aft line of the model and either in front of or behind the wheels. The member carrying the claws is connected with a vertical spindle to the upper end of which is secured a horizontal grooved pulley wheel. A thread is passed around the pulley, the two ends of the thread, which may be of being held in the hands of the operator. When the model is placed on a surface covered with a suitable material such as cloth, baize, or a stretched sheet and the pulley is turned so that the points of the claws are pointing backward,

any oscillation imparted to the pulley by pulling either end of the thread will cause one claw to be withdrawn and the model take a step forward about the-other claw as a pivot. If the pulley is rotated in opposite directions alternately through equal arcs, the model will progress forward in a constant direction. Successive 'movements of the pulley in the same direction will alter the course, so that the model can, consequently, be steered to follow any required path.

In the accompanying drawings, which represent examples of modelships according to the invention, Figure 1 is a side elevation of a ship; Fig. 2 is a rear view; Fig. 3 shows in side elevation a ship with slightly modified means for propulsion. and Figs. 4. and 5 show details of the propelling device. Referring to Figs. 1 and 2, A is themodel ship, B, B are wheels mounted on trans- Specification of Letters Patent. Patented DEC, 2, 1919, Application filed May 26, 1919. Serial no. 299,724;

verse axles b, 6 C is amember provided with claws 0, 5- shown on a larger scale in Figs. l and 5 andplaced in the fore and aft line of the model. A grooved horizontal pulley D'carries a verticals spindle d to the lower horizontal extension 0 of which the member C is pivoted. This arrangement enables the ole ws 0, 0 to pass easily over an uneven surface. The points of the claws are bent backward and are adapted to engage with a suitable surface, so that oscillations imparted to the pulley Wheel D cause, as explained above, the model to progress in any required direction. A thread F is passed preferably about twice around the grooved pulley D; thisthread is guided in a wire guide G supported by a loose sleeve o surrounding the spindle (Z and placed bea tween. the pulley D and the deck of the vessel. The member C can be inclined at any angle to the fore and aft line and the course altered accordingly The thread is of suflicient length to enable the operator to be at any convenient distance from the model.

Models may be driven tandem by the same thread passing around each pulley, if the pulleys have the same diameters and there is the same ratio between the diameters of the pulleys and the distance apart of the claws,

' The models are loaded with weights disposed between the wheels and the clawed member.

In the modification shown in Fig. 3 the pulley D is smaller and is connected with the member C by gearing H, H.

Having thus described the nature of the said invention and the best means I know of carrying the. same into practical effect, I claim 1. A mounting for model ships, tanks and the like, comprising a pair of wheels on the same transverse section of the model and a member on the fore and aft line provided with claws, adapted to engage with the material on which the model is placed, a verti- V cal spindle secured to the model, a pulley on the spindle, manually operated means for imparting oscillations to the pulley and means connecting the spindle to said mem: her.

2. A mounting for model ships, tanks and the like, comprising a pair of wheels on the same transverse section ofthe model and a with claWs, adaptedto engage with the ma- 4 terial on which the model is placed, a Ver- 'tical spindle, a grooved pulley associated with said spindle, a thread in the groove of said pulley adapted to be manually manip'ulated to impart oscillations to the spindle and means connecting the spindle to said member.
